Hello everyone: I tried following the instructions on this page to set up a VNC server: http://wiki.centos.org/HowTos/VNC-Server I can telnet to port 5901 from the machine itself: # telnet 127.0.0.1 5901 Trying 127.0.0.1...

Hello: I just did a fresh install of CentOS 6.2 on a virtual server. I am trying to configure Postfix but it does not seem to be reading configuration directives from /etc/postfix/main.cf Here is what I did to test it: vi /etc/postfix/main.cf and set this directive: myorigin = hello.world.com postfix reload postconf -d | grep myorigin I get this output: append_at_myorigin = yes myorigin =

Are "centralized" database (SQL) servers best left out of virtualization and committed to their own hardware like the "old days" or are there some guidelines one should consider in setting them up? I'm not talking mega-large recordsets, but large enough to handle multiple years of CRMs and intensive querying, Accounting Systems and so forth. Fundamental website CMS

Hi buddies I attempt to compile a kernel on CentOS 5.3. The kernel version is 2.6.31.6. All make procedure is running ok. I can generate initrd image with no problem too.

Hello: I am using a CentOS server as a KVM host using bridged networking for the guest servers. I would like to limit the bandwidth available to a guest. I tried using the tc command, but it is only limiting the download speed to the guest. Is there a way to limit the upload speed from the guests?

I have always been able to browse, without any problems, http://www.mobile-review.com/index-en.shtml but for the past 2 or 3 days, Mozilla Firefox just hangs "connecting to ...." How can I tell if they have started blocking IP addresses from Colombia? I would like to do that, before I post to the IPCop mailing list. I have my IPCop box set up to do DNS Caching, so possibly something

I need to configure a small proxy appliance which doesn't require a lot of CPU power. I'm looking for any warnings this group may have regarding CentOS-5 on the following: - Acer AspireRevo 3610 (Atom CPU) - Dell Inspiron 537s (Celeron) - Any other small machines you might recommend (UL approved) I need to implement dual NICs, and for the Dell it should be no problem finding a

just to follow on my earlier post, i have pointers to a couple commercial C/W manuals for RHEL administration, but both of them use an entire chapter discussing virtualization using Xen. i'm under the impression that RH is firmly in the KVM camp (at least for now), and that learning Xen on red hat/centos wouldn't be as useful as learning KVM. thoughts? rday --

Hello: According to this list of supported guest on RHEL 5.4 KVM: <http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Virtuali zation_Guide/chap-Virtualization-KVM_Restrictions_and_support.html> http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Virtualiz ation_Guide/chap-Virtualization-KVM_Restrictions_and_support.html RHEL and some Windows guests are

Hello: I am wondering if KVM is ready for production for running a Windows Server 2003 32 bit guest. According to the RHEL 5.4 virtualization guide, there is supposed to be a virtio-win yum package, but that was not released. Instead, it looks like that is only available for RHN subscribers. Also, I saw this posting on the CentOS list: --- Quoted from CL Martinez There are freely

First, I'm trying to following along on a document on "SecurityFocus" on "Securing MySQL: step-by-step". I'm on step 3.8 "Test the configuration". I have my CHROOT directory structure setup and the chrootuid is failing (haven't figured that one out, yet). So, I simply tried a 'chroot /chroot/mysql' and got: chroot: cannot run command

Hi All, I have a CentOS 5.4 web server. I have some stuff that runs on 443. When I hit https://<the site> The user gets a warning saying that site identity could not be verified and the user can add an exception if they want. How do I stop this from happing?

Adobe doesn't seem to have acroread for x86_64 linux, or at least I don't see it anywhere. Anybody know otherwise?

Howdy, I tend to try out many open source apps/packages - games, editors to media tools. I have a bad habit of downloading and extracting source in the /var/tmp directory and then doing configure-make-install process. I am not sure of best practice (good practices) to be followed when installing any software. For example how and where to keep the src. Any comments and/or resources would be really

Hello: One of my customers asked for access to stop and start their VPS. Right now, I can do that using virsh, but I do not want to give this customer the ability to stop and start all VPSs running on the host. Is there a way to give stop and start control of one VPS to someone? I am using KVM on a CentOS 5.5 host. Thanks, Neil -- Neil Aggarwal, (281)846-8957 FREE trial: Virtualmin VPS

My 12 year old wants to learn more about servers and has memorized a lot of commands like ls, chmod, du, etc. He wants to have his own domain and server on the web and I have enough Static IP's, so why not foster this interest. I have an old ultra sparc 5. Are there any CentOS versions that support Sparc? Or recommendations? I know OpenBSD does, but I am more versed in Solaris and versions
